Document Type and Number:
WIPO Patent Application WO/2021/190004
Kind Code:
A1
Abstract:
A personnel positioning system and a risk assessment method in foundation pit construction. The system comprises: a plurality of ground surface settlement detection units (1) provided on the ground surface (6) of a foundation pit and a plurality of personnel positioning units (2) provided on the side wall of the foundation pit. Each ground surface settlement detection unit (1) comprises: a ground surface settlement detector (1.1) and a data acquisition module (1.2), and each personnel positioning unit (2) comprises: a box body (2.1), an information acquisition module (2.2) and a transmitting antenna (2.3); the data acquisition module (1.2) receives ground surface settlement information acquired by the ground surface settlement detector (1.1), the information acquisition module (2.2) receives the ground surface settlement information sent by the data acquisition module (1.2) and acquires personnel location information by means of personnel identification cards (2.4), and the transmitting antenna (2.3) sends the ground surface settlement information and the personnel location information to a remote server. Unified management of the personnel location information and the ground surface settlement information is achieved by combining the personnel positioning units (2) and the ground surface settlement detection units (1), and the problem that personnel positioning is difficult when danger occurs in the foundation pit engineering construction process is avoided.
